to be employed by metal Workers for carryi The tool holder or device 1Q has a handle ing chisels or cutting blades so as to permit 11 and a head 12 both of which may be of '3Q them to be properly and readily utilized 4any desiredsize or'shape. The head 1.2 is especially While trimming and shaping metal preferably circular in shape, and has a memin a lathe or like machine, and which is of bei' or supportingplate 13 and a rotatable a form to permit a number of chisels of vamember or adpisting plate 14:.. The mem- Fious shapes to be held therein so as to faciliber or supporting plate 13 is integrally 75 tate Work While using the implement by obformed upon one end of the handle 11, and viating the necessity of changing the chisel has a central opening 15 therethrough. Adlwhen it is desired to use different kinds at )acent to the circumferential edge of the separate intervals as is incident to holders in member 13 are three spaced orifices 16, 17,

18 all of which may be smaller in size than 80 ordinary use.

Another object'of the invention is to prothe central opening 15. Upon the underside of the member 13 is a circular `guide or y vide a form of head for the tool holder wherein is employed an adjustable member ring 19 which is inte rally formed u on said member, and is of ess diameter t an the or plate which serves to permit each chisel member 13 whereby an annular counter- 35 sunken edge 19 is provided. The circular guide or ring 19 is also of a width so that an annular countersunken portion, as 20, is provided centrally of the underside of the mem ber 13 and around the opening 15 thereof. 90 In the ring 19 as Well as in the member or supporting plate 13 and substantially midway between the orifices 16 and 18 are recesses 21 and 22.

tervals for use, and still another object of the invention is to provide a locking element for holding the adjustable member against movement when one of the chisels is positioned.

A further object of the invention is to provide means servingl to permit each of the. chisels to be removably held in the head of the holder and which is adapted to securely lock the chisel against displacement. The member 0r adJustmg plate 14 maybe 95 A practical embodiment of the invention C1IC11la-r lnvshape, and has a central opening is represented in the accompanying draw- 23 which is adapted to be registered with ings, forming a part of this specification in the Opening 15 when said member and the which similar characters of reference indimember 13 are assembled. Upon the outer t5 cate cm'responding parts in all the views, `edge of the top surface of the member or 1.00 the said invention being more fully dead3ust1ng plate 14 1s an annular flange 24, scribed hereinafter and their pointed out in and also upon the top surface of said memthe appended claims. ber and around the edge of the opening 23 In the drawings, Figure 1 is an inverted lis a ring 25. When the members 13 and 14 mplan, partly broken away, of une form of are assembled the annular ange 24 and the 105 tool holder embodying my invention. Fig. ring 25 are adapted to be seated in the an- 2 is a top plan, partly broken away, of the nular countersunlren edge 191 and received tool holder. Fig. 3 is a side elevation, partly in the annular countersunken portion 20, re-

broken away, of the tool holder. Fig. 4 is spectivcly, of the member or supporting no of the member -14 when rotated. In the top surface of the member or adjusting plate 14 and between the annularV flange 24 and the ring 25 are provided recesses 26, 27, 28, 29 which are adapted to register with the openings 16 and 18, and the recesses 21 and 22 when the members are assembled. The underside of the member or adjusting plate 14 and surrounding the edge of the opening 23 is a cut-out portion, as at 30, which communicates with said opening, and through the wall of said member or adjusting plate are provided radiallydisposed passages 31, 32, 33, 34 each of which is preferably square in shape so as to carry therein a chisel or cutting blade 35, 36, 37, 38.

In assembling the member or supporting plate 13 and the member or adjusting plate 14, a pivot in the form of a bolt, as 39, is employed. The bolt 39 has a threaded end 40, a circular neck 41, and ahead 42. As shown in Fig. 2, the bolt 39 is passed through the opening 23 of the member 14 so that the head 42 will rest upon the seat of the recess 25" 30 of said member, and the bolt is then guided through the opening 15 ofthe meinber13 so that its threaded end 40 will eX- tend beyond the top surface of said member 13. The bolt 39 is adapted to be held rigidly in the member 13 and this is accomplished by the use of a key, as 43, thus permitting the member or adjusting plate 14 to rotate freely upon said bolt. In order to properly position one of the chisels when it is desired to use the implement, the member or adjusting plate 14 is rotated upon the bolt 39 one-fourtli of a circle so thatthe chisel to be used will be positioned to extend beyond the wall of the head which is opposite to the handle 11 and in alinement therewith. By rotating the member 14 in like manner it is evident that any one of the chisels may be kreadily positioned for use, and serving to indicate a fixed position for one of the chisels when its use is desired, in each of the recesses 21 and 22 of the member 13 is a yielding stop 44.

Each of the yielding stops 44 consists of a lball 45 one of which is seated in each of the recesses 21 and 22 of the member 13, and between each of said balls and the seats of said recesses is a spiral spring 46 which normally serves to yieldingly force the balls e towardA the member 14. Each of the balls 45 are adapted to engage one of the recesses 26, 27, 28, 29 of the member 14 so that the rotation of said member will be yieldingly prevented from further movement when the l. balls are guided into two of the opposed rethe chisels is cesses of the member 14. In this manner the proper position for one of the chisels for the members 13 and 14 together when one of positioned, I employ a locking element, as 47.

The locking element 47 is composed of a plate 48 having the opposite parts thereof cut-out whereby two substantially triangular portions, as 49 and 50, are provided. A portion of the underside of the corresponding edge of each of the triangular portions 49 and 50 is beveled, at 5l, and upon the top of the plate 48 is a nut 52 which is screwed upon the threaded end 40 of the bolt 39 so as to rotatably hold said plate upon the top surface of the member 13. In each of the orifices 16 and 18 of the member 13 is a movable locking pin 53, and each of said pins has a head 54 and a shank 55. Encircling the shank 55 of each of thenlocking pins 53 is a spiral spring 56 normally serv- ,ing to force the head 54 outwardly of the orifices 16 and 18 in which it is held, and the free end of the shank of each of said pins is adapted to engage one of the recesses 26, 27, 28, 29 of the member 14 when in register therewith bythe rotation of said member. In order to operate the element 47 for locking the member 14 to the member 13 when l one of the chisels is positioned for use, the" -plate 48 is revolved upon the bolt 39, and' each of the beveled edges 51 of the triangular portions 49 and 50 will engage one of the heads 54 of the locking pins 53. One

of the Shanks 55 'of the'pins 53'will be forced 'l into one ofthe recesses 26, 27 ,i 28, 29 of the member 14 which will then beheld against movement, and to limit the movement of the :locking element '47. vastop 57 is provided upon the top surface of the member 13.

For the purpose of'securingleach of the g chisels 35', 36, V37', 38 :when'inserted in the passages 31,32, 33,"341of1the member or ad' justing plate 14', through the wall ofthe ad` justing plate and atan angle with respect to therein for reception of a key by whichl said bit is moved to engage one ofthe chisels forl holding it tightly in the member 14, orfor l releasing the engagement when it is desired' to remove the chisel from the implement.` In the foregoing description I have em-v bodied the preferred lform of my invention,

but I do not wishto be understood as limiting myself thereto, as I am aware that modifications may be made therein without de-4 parting from the principle or vsacrificing any of the advantages `of this invention,

therefore I reserve to myself the right to make such changes as fairly fallwithin the` A 4scope thereof. use may be indicated, and to securely lock.' i
